MARTIN EVENSQN, OF HUDSON, WISCONSIN.

WINDOW-FRAME.

To all whom it may concern:

Be it known that I, MARTIN EvnNsoN, citizen of the United States, residing at Hudson, in the county of St. Croix and State of Wisconsin, have invented new and useful Improvements in Window-Frames, of which the following is a specification.

This invention relates to window frames or casings, and it has for its object to produce a metal lined frame of simple and in expensive construction.

A further object of the invention is to produce a metal lined window frame in which detachable parting strips shall be dispensed with and which may be readily adjusted so as to fit window sashes of slightly varying thickness, thereby producing a close and exact fit, enabling the sashes to move freely and unobstructedly and avoiding leaky and open joints.

With these and other ends in view which will readily appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described and particularly pointed out in the claims.

In the accompanying drawings has been illustrated a simple and preferred form of the invention, it being, however, understood that no limitation'is necessarily made to the precise structural details therein exhibited, but that changes, alterations and modifica tions within the scope of the claims may be resorted to when desired.

In the drawings,-Figure 1 is anelevation of awindow frame constructed in accordance with the invention, as seen from the outside of a building, the sashes being removed. Fig. 2 is a vertical sectional view taken on the line 2-2 in Fig. 1. Fig. 3 is a horizontal sectional view taken on the line 33 in Fig. 1. Fig. 4 is a horizontal sectional view taken on the line l4 in Fig. 1. Fig. 5 is a sectional detail View, enlarged, taken through the lining.

Corresponding parts in the several figures are denoted by like characters of reference.

The window casing or frame includes the customary sill 1, side members or jambs 2 and a cap 3. In the construction of the side members or jambs and of the cap any inexpensive solid wood may be used, these parts being protected by the metallic lining to be presently described. It will also be observed that, movable parting strips being Specification of Letters Patent.

dispensed with, the jambs and the cap do not require to be grooved for the reception of such parting strips, and the cost of manufacture of these parts will, therefore, be much reduced.

The metallic lining for each jamb is composed of two strips or pieces A and B of sheet metal, such as ordinary sheet steel of suitable thickness to preserve its rigidity for the purposes of the invention, said sheet metal being preferably galvanized or otherwise protected against corrosion. The outer strip A has a flap 3 underlying the outside casing 4, and said strip is crimped or bent to form an outside stop 5 which is positioned adjacent to the outside casing. The strip A is bent adjacent to its inner edge to form a tongue 6 having a reverse bend 7 combining therewith to form a groove 8 adapted to receive the edge of the strip B, as will be presently seen. The side jamb has a slight recess or groove 9 to receive and accommodate the seam formed by the tongue 6, the reverse bend or flange 7 and the edge of the strip 13 introduced therebetween, as will be presently seen. The tongue 6 should be formed at a distance from the stop 5 equal to or slightly less than the thickness of the top sash which is to be accommodated in the casing; this is in order that proper adjustment may be subsequently made.

The strip B, which constitutes the inner lining strip, is bent to form adj acent to its outer edge a parting stop 10 and a tongue 11, the latter being adapted to engage the groove 8 between the tongue 6 and the return bend 7 of the strip A. The inside stop, which consists of a molding of wood or other material overlies the inner edge of the strip B. In assembling these parts of the device the strip A is secured in position, partly by means of the outside casing which overlies the flap 3 and which may be secured by nailing upon the j amb 2, as indicated at 13. The strip A is, furthermore, secured by small nails 14 driven through the projecting portion of the flange 7 into the body of the jamb. The strip B is secured by engaging the flange 11 in the groove 8; after pushing the strip in an outward direction until the parting stop 10 is properly adjusted with respect to the top sash, (not shown) the strip B is secured by nails 15 driven through the stop 12 into the j amb. The cap 3 is lined with strips A and B constructed and arranged in every respect like the strips A and fit snugly in the guideways the pockets or perfect joints.

B; the strip A being 3, an outside stop 5 and with a tongue 6 and reverse bend 7 combining to form a groove 8, the seam being accommodated in a groove or recess 9 in the cap. The strip 13 is provided with a parting stop 10 and with a flange or tongue 11, nails 15 driven through the inside stop 12.

It will be observed that by the construction set forth adjustment with respect to the thickness of the top and bottom sashes may be readily made so as to cause the sashes to provided for their reception and to avoid leak-y and im- This is partly accomplished by proper adjustment of the strips B, B with respect to the strips A, A, and partly by properly positioning the stops 12 and 12, as will be readily understood.

It will be seen that by removing the stops 12 and the strips B from the jambs or side members, access may be conveniently had to openings 16 which are cut in said side members for the passage of the sash weights. Slots 17 are out in the strips A and'B to accommodate the pulleys 18 over which the weight carrying cords 19 are guided. It follows that access may be very conveniently had to the sash weights and cords when necessary in order to make repairs, without disfiguring the window frame or casing. v

The metallic lining may obviously be painted, stained, grained, varnished or otherwise embellished to correspond with the appearance of the woodwork or in any desired ornamental manner.

As will be seen from the foregoing description I have provided a simple and efficient metallic-lined window frame or casing which may be easily installed; which may.

be produced at a very moderate expense not necessarily exceeding that of frames or casings of ordinary construction; which will permit the free working of the sashes under all circumstances; in which repairs may be made without having to remove parting strips and the like; and it entirely avoids the use of parting strips which are liable to Copies of this patent may be obtained for provided with a flap,

and it is secured by her and the outer distance between become displaced and interfere with the working of the sashes.

Having thus described the invention, what is claimed as new, is

1. In a window casing, a wooden jamb and lining strips for the same comprising a strip bentto form an outer stop and a groove forming part of a slip seam, and an inner strip bent to form a parting stop and having adjacent to said stop a tongue engaging the groove and forming part ofthe slip seam, said inner strip having also a flat portion extending inwardly from the stop and overlying constituting an'inner stop, overlying the flat portion of the strip that overlies the jamb and secured adj ustably with respect to the parting stop.

2. In a window frame, a pair of jambs, a

. cap, and metallic linings for said jambs and 1 cap, said linings havlng outer stops,

comprlsing outer strips inner strips having parting stops and slip seams connecting the inthe outer stops and the parting stops to be varied, in combination with inner stops secured independently in 7 adjustable relation with respect to the parting stops. o

3. A window frame comprising a sill, jambs and a cap, in combination with metal- ;lic linings for said jambs and cap comprising :outer strips having flaps lying adjacent to :the outer faces of the jambs and the cap, said strips being provided with outer stops, inner strips having parting stops, slip seams formed by contiguous parts of the inner and the outer strips, and inner stops overlying the inner strips, said inner stops being secured adjustably with respect to the parting stops by nails passing through the inner strips andthe inner stops and engaging the jambs and the cap.
